Remember to Blink
Why Blinking Is Essential for Healthy Eyes and Improved Vision
By Dr. Ben Kim
Are you interested in taking optimal care of your eyes and experiencing your best vision? If so, I encourage you to learn how to make soft and frequent blinking a subconscious habit.
Frequent and gentle blinking is essential to the health of your eyes and vision because it allows your eyelids to regularly coat your eyes with three beneficial layers of tears:
The first layer of tears lies right up against the whites of your eyes, and provides an even coat of protein-rich moisture for the second layer to adhere to.
The middle watery layer helps to wash away foreign debris. It also nourishes the cornea of your eyes with minerals, a variety of proteins, and moisture.
The third outer layer of tears is somewhat oily. It serves to prevent the middle watery layer from evaporating quickly, and provides needed lubrication between your eyes and your eyelids.
If your eyes are not regularly coated with the three layers of tears described above, they will be deprived of ongoing nourishment and cleansing, and they will be unnecessarily strained.
One of the reasons why many of us don't blink as often as we should is that we don't see frequent blinking in mainstream media. Actors and anchor-people are typically trained to blink as infrequently as possible, so when we take in mainstream media, our subconscious minds learn that it isn't normal to blink frequently.
To optimally support your eyes and vision, it's best to blink softly every two to four seconds, which translates to about fifteen to thirty blinks per minute. By consciously making an effort to softly blink at this rate, over time, your body will turn your conscious efforts into a subconscious habit.
Here are some notes on blinking to promote optimal eye health and vision:
A soft and natural blink should occur like the light flap of the wings of a butterfly - this is a good image to visualize as you make an effort to blink softly every two to four seconds.
You should blink regularly during all activities, including reading, working on the computer, and viewing a TV program or film.
Contact lenses can discourage frequent blinking because the back surface of your eyelids is not designed to rub over an artificial surface. This is one of several good reasons why contact lenses should be avoided whenever possible. For more information on this topic, please view: Potential Dangers of Contact Lenses
Some yoga and meditation instructors suggest doing exercises that involve fixating your vision on one object, such as the flame of a candle, and doing your best not to blink. If taking good care of your eyes and vision is a top priority, I encourage you to ignore the part about suppressing your instinct to blink. It's quite possible to experience inner stillness and peace while blinking frequently.
Since the primary goal of blinking regularly is to keep your eyes well lubricated and nourished, another good tip for eye and vision care is to keep your eyes closed whenever you are thinking about something while you do not need your vision. For example, if you are stuck in the middle of composing an e-mail message, close your eyes while you think of your next sentence.
